Description
Citric acid monohydrate is an analytical-grade organic acid supplied at min. 99,5 % p.a., ACS and ISO quality for laboratory reagents and reference use. The empirical formula is C₆H₈O₇·H₂O, molar mass 210,14 g/mol and density 1,54 g/cm³; the boiling point is reported above 170 °C. CAS number 5949-29-1 and EG nr. 611-842-9 apply. This monohydrate form is widely employed in buffer systems, pH adjustment, complexometric work and environmental or food-related analytical preparations where a defined citric acid source is required. from manufacturer Carl ROTH provides a convenient stock quantity for routine method development and sample preparation. Crystalline handling is straightforward under standard laboratory conditions. Specify this p.a./ACS/ISO grade when protocols call for high-purity citric acid monohydrate rather than anhydrous material, and consult the safety data sheet for correct storage and personal protection during weighing and dissolution.
